Objectives: Evaluate the fatigue resistance and failure mode of novel-design implant restorations made of histoanatomic computer-assisted design/computer-assisted manufacturing (CAD/CAM) bilaminar bonded assemblies.
Material And Methods: 60 screw-retained implant restorations were fabricated. Monolithic restorations were used as a control group (15 lithium disilicate: group CE; and 15 nanofilled composite resin: group CL), and compared with bilaminar restorations (15 dentin-shaped lithium disilicate mesostructures with a bonded nanofilled composite resin veneer: group CEL; and 15 dentin-shaped nanofilled composite resin mesostructures with a bonded lithium disilicate veneer: group CLE).
Chagas disease is an anthropozoonosis from the American continent that has spread from its original boundaries through migration. It is caused by the protozoan Trypanosoma cruzi, which was identified in the first decade of the 20th century. Once acute infection resolves, patients can develop chronic disease, which in up to 30-40% of cases is characterised by cardiomyopathy, arrhythmias, megaviscera, and, more rarely, polyneuropathy and stroke.

The authors aimed to investigate whether changes in PbtO after DC could be used as an independent prognostic factor. METHODS The authors conducted a retrospective, observational study at 2 university hospital ICUs.

The phellogen (cork cambium) externally produces cork (phellem) cells that are dead at maturity; while metabolically active, these tissues synthesize cell walls, as well as cell wall modifications, namely suberin and waxes. Suberin is a heteropolymer with aliphatic and aromatic domains, composed of acylglycerols, cross-linked polyphenolics and solvent-extractable waxes.

Patients And Methods: Retrospective case series.
Plasmodium falciparum stage V gametocytes are responsible for parasite transmission, and drugs targeting this stage are needed to support malaria elimination. We here screen the Tres Cantos Antimalarial Set (TCAMS) using the previously developed P. falciparum female gametocyte activation assay (Pf FGAA), which assesses stage V female gametocyte viability and functionality using Pfs25 expression.

Objectives: The purpose of this study was to determine whether posaconazole alone or combined with benznidazole were superior to benznidazole monotherapy in eliminating T.
Specific chemotherapy using benznidazole (BNZ) for Chagas disease during the chronic stage is controversial due to its limited efficacy and toxic effects. Although BNZ has been used to treat Chagas disease since the 1970s, few studies about the biodistribution of this drug exist. In this study, BNZ tissue biodistribution in a murine model and its pharmacokinetic profile in plasma were monitored.

Despite its toxicity and low efficacy in the chronic phase, benznidazole is the drug of choice in Chagas disease. Scarce information about pharmacokinetics and pharmacodynamics of benznidazole has been published. We performed a phase I, open-label, nonrandomized pharmacokinetic study of benznidazole (Abarax) conducted with 8 healthy adult volunteers at the Infectious Diseases Department of the Vall d'Hebron University Hospital (Barcelona, Spain).

True infection occurs after accidental ingestion of ants containing metacercariae and spurious infection through the consumption of infected animal liver. Differential diagnosis between true and pseudo-infections is performed through stool examination after a diet free of liver.

Introduction: The aim of the present study was to evaluate clinical presentation and management of sigmoid volvulus in children. Sigmoid volvulus is one of the three leading causes of acute obstruction of the colon and is between 50 and 90% of all large bowel volvulus. In the pediatric population only 3 to 5% of bowel obstructions are caused by volvulus and there are less than 100 cases reported in the literature.

For this purpose two sets of SPOT5-PAN images have been used, which are in turn used for Change Detection Indices (CDIs) calculation. For minimizing radiometric differences, a methodology based on zonal "invariant features" is suggested.

Few dengue fever cases (n = 3) and no cases of chikungunya were documented during the 2013-15 Brazilian winter months, August and September, the period when the Games will be held. The main diagnoses were dermatological (37%), gastrointestinal (30%), febrile systemic illness (29%) and respiratory (11%).

According to the WHO, chronic Chagas disease (CD) diagnosis is based on two serological techniques. To establish a definitive diagnosis, the results must be concordant. In cases of discordances, the WHO proposes repeating serology in a new sample, and if results remain inconclusive, a confirmatory test should be performed.

Methods And Results: We selected 485 patients in the chronic phase of CD from two Spanish settings.
Physical dormancy of seed is an adaptive trait that widely exists in higher plants. This kind of dormancy is caused by a water-impermeable layer that blocks water and oxygen from the surrounding environment and keeps embryos in a viable status for a long time. Most of the work on hardseededness has focused on morphological structure and phenolic content of seed coat.

Recent studies have demonstrated that DMSO and EG cause large transient increases in intracellular Ca(2+) in mouse oocytes. The CP used in vitrifying protocols also increases the intracellular calcium transient.
